Any changes in blood test of a child cause in parents' experiences, especially if the number of white blood cells changes, it is known that such cells are representatives of the immune system. If the mother sees an excess of lymphocytes on the form of the analysis or hears the word "lymphocytosis" from the doctor, she wants to know what it is, from which such blood cells are raised and whether the high level of lymphocytes for the baby is dangerous.
When the level of lymphocytes is increased
The body count just born babies are not very many, because their immune system is not yet fully operational. But a few days after birth, the number of lymphocytes begins to increase and up to 4 years of age exceeds the number of other types of leukocytes.
At about 4-5 years, the level of lymphocytes and neutrophils becomes equal, after which the number of neutrophils begins to predominate.
upper limit of the norm of lymphocytes in children think:
A newborn baby
On the 5th day of life
With 10 days to a year
In children 1-5 years 65%
In children older than5 years 55%
In children older than 10 years
If the result of the analysis showed an increased number of lymphocytes in excess of these figures, it is called lymphocytosis .It is relative if the number of lymphocytes does not exceed the norm, but only seems to be overestimated because of a decrease in the level of other leukocytes. The total number of white blood cells can remain normal or be increased.
absolute lymphocytosis also occurs, caused by an excess of lymphocytes in the peripheral circulation due to their formation activity in the bone marrow and other places or insufficient destruction in the spleen.
Causes of lymphocytosis lymphocytosis
To diseases, due to which in the blood of children are inflated lymphocytes, include:
- Viral hepatitis.
- Infection caused by adenovirus.
- Chicken pox.
- Herpes infection.
- Infection with HIV.
- Infectious mononucleosis.
- Enterovirus infection.
- Whooping cough.
- Infection with cytomegalovirus.
- Infection with parasites or protozoa.
- Leukemia, which can be both acute and chronic lymphatic leukemia.
- Malignant thymoma.
- Non-Hodgkin's lymphoma.
- Smith's disease is a rare infectious disease with lymphocytosis.
- Franklin disease. This is called another rare pathology, in which lymphoid tissue proliferates and the production of immunoglobulins increases.
However, a high percentage of lymphocytes is not always associated with a viral infection or a tumor process. If lymphocytosis is relative, the cause of this result of the blood test is factors that reduce the number of other types of white blood cells, , for example, neutropenia due to vitamin B12 deficiency or the use of certain drugs that depress neutrophils.
. Also, non-infectious causes of the appearance of lymphocytosis are:
- Arsenic or lead poisoning, as well as carbon disulphide or tetrachloroethane.
- Autoimmune diseases.
- Bronchial asthma.
- Removal of the spleen, resulting in the blood cells can not be disposed of in the right amount.
- The effect of certain medicines - medicines against epilepsy, hormonal drugs, antibiotics, narcotic analgesics and others.
It should be separately noted that after recovery, the level of lymphocytes does not immediately return to normal levels. In most children, within a few weeks, and sometimes months, after the disease is over, lymphocytes will be detected in increased numbers, but gradually their level will decrease.
The opinion of Komarovsky
What to do
If a child has not only increased lymphocytes, but also monocytes, this will lead the doctor to think about a chronic viral infection. Also, with a protracted infectious process, children are referred for analysis, which determines activated B cells. If activated lymphocytes in a child's blood test exceed a normal rate, this may be a sign of an autoimmune process.
How to determine the type of infection using lymphocyte counts, see E. Komarovsky's video:
Having learned why a child has lymphocytosis, the doctor will prescribe suitable therapy. In many cases, this change in the cellular composition of the blood simply indicates the active resistance of the child's immune system to the infectious disease .And therefore, no drugs that reduce the number of lymphocytes are required.
The child is provided with the correct sleep regime, sufficient rest, walking outdoors, full nutrition. This contributes to a quick recovery and normalization of well-being, supports the immunity of the baby and helps to normalize the number of lymphocytes in his blood.
To prevent the increase in lymphocytes in the blood of a child, parents should focus on strengthening the immune system of the daughter or son:
- Provide the child a balanced diet.
- Encourage moderate physical activity and exercise.
- Dressing a child on the weather, avoiding hypothermia.
- Do not allow the child to develop bad habits.
- Every year to check blood for timely detection of diseases.
